This test is to determine the function of the terminals on a 4 prong rectifier.
This information was provided by stepthrutuner.
Ringing out your (bridge) rectifier is very easy to do with your DVM.
With your meter set for diode testing, probe all possible combinations across the four pins. The two pins that give the highest readings are the + and -. The pin that your black (ground,common) probe is against is the positive terminal and the red probe is against the negative terminal. The connections to the other two terminals from your stator output(s) can go either way.
I have checked this out with a spare bridge rectifier I had on hand and know this to be true. The lower readings should be around 0.4 - 0.6 and that highest reading should be around 0.7 - 1.0v.
Hope this helps. It's almost impossible to damage a bridge rectifier by hooking it up wrong. It just won't do what it is supposed to do which is to put out a dc current with an ac ripple on top of the waveform.
